There will be zombies
Video games, unlike other works of fiction such as books or films, use genres based on their gameplay interaction rather than visual or narrative differences. So genres have it's own section and the settings section more or less fit the genres of books and films. It's not uncommon for a game to belong to several genres and settings at once. The setting is not only physical place. It gives the time period, the history and so on.
